CONSTRUCTION OF WALLS.

SPECIFIATION formngpart of Letters Patent No. 528,636, dated November 6,1894.

Application filed June 25, 1894. Serial No. 515,798. (No model.)Patentedin Luizemburg, March 28. 1894, No. 2,001, and in Belgium April16, 1894.No.109,207.

To all whom it may concern:

Be it known that I, LAMBERT KPPER, manufacturer, a citizen of the GermanEmpire, residing at Aix-la-Chapelle, in the Kingdom of Prussia, Germany,have invented certain new and useful Improvements in the Construction ofValls, (upon which I have received patents in the following countries:Grand Duchy of Luxemburg, March 28, 1894, No. 2,001, and Belgium, April16, 1894, No. 109,297,) of which the following isa specication.

My invention relates to improvements in the construction ofbuilding-walls. I attain these objects by the combination illustrated inthe accompanying drawings, in which- Figure 1 shows the front view ofthe building-wall, partly in section, to illustrate the newconstruction. Fig. 2is a longitudinal sectional viewof thebuilding-wall; Fig. 3, a detail vertical section of a single plate; Fig.4, a side view of the same.

Similar letters of reference' indicate corresponding parts throughoutthe several views.

The building-wall, as shown in Figs. l andy 2, is composed of plates aunited together, which are provided upon their vertical edges withgrooves b from which a number of short channels or perforations c branchoff laterally toward the inside of the plates. On connecting the platestogether, the channels formed by the grooves b at the edges whichcoincide with each other and with the upper part CZ of the medianchannel of the adjacent lower plate are filled together with theirramiications c and the channel part d with a binding material. In thisway an utmost solid and rm connection of the plates is created andthrough the action of the ramifications` the plates are sustained intheir vertical edges. Thus, a reciprocal displacement of the same isimpossible and the wall forms a steady ensemble by which means thepressure of the same on the supports is released. The other in thechannels c and the upper part d of the median channel to escape duringthe filling with binding material, the channels at their end surfacesare supplied with small openings e, which are ending in the edjacentinsulation channels.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. A building-wall composed of plates a provided in the middle with achannel divided in two or more parts and upon their vertical edges withgrooves?) from whicha number of short channels c branch off laterallytoward the inside of the plates, substantially as described.

2. A building wall composed of plates d the grooves upony their verticaledges together with their ramifications and the upper part d of themedian channel'of the adjacent lower plate being filled with a bindingmaterial, substantially as set forth and for the purpose specified.

8. A board or plate for building-walls whose grooves upon their verticaledges are provided with ramifications directed toward the inside of theplate, substantially as set forth.

In'testimony that 1 claim the foregoing as my invention I have signed myname in the presence of two subscribing witnesses. t
